What is the effect of pressure on vascular resistance and tissue blood flow?

Does increased arterial pressure increase or decrease vascular resistance?

What is critical closing pressure?

There are two factors in this question I think:

  1. The physics of flow in closed rigid circuits
  2. The physiology of the human body

In physics terms pressure doesn't affect resistance. Flow is a function of pressure
